Hello catfish freaks,
today I would like to introduce you in two articles of the current issue of Aquaristik Fachmagazin:
Ingo Seidel “The Santarém-Hypancistrus (L450) – a little-known pleco” (“Der Santarém-Hypancistrus (L450) – ein kaum bekannter Harnischwels”)
Ingo talks about his experiences with Hypancistrus sp. “L 450”. Only the company Transfish, Munich imported this Hypancistrus-form of Rio Xingu 10 years ago. Some month later, Sven Seidel could increase these species in the Welsladen Chemnitz.
Ingo have group of Hypancistrus sp. “L 450”. This group consists of three plecos and lives together with Ancistomus sp. “L 387” and Ancistrus sp. “L 486” in one tank. The propagation occurs easily in tap water from Berlin. Advantageously, Ingo make two great water changes per week with slightly colder water.
The rearing is unproblematic in the parent’s tank.
Ingo Seidel “Pleco worlds – worth knowing, news and unusuals” (“Welswelten – Wissenswertes, Neues und Ungewöhnliches”)
Ingo ask “L174 – doomed to extinction”. The dam of Belo Monte on the Rio Xingu was completed months ago. With him a river loop, the so-called Volta Grande was divided and now only sparsely supplied with water.
Hypancistrus zebra (L 46) and Hypancistrus sp. “L 174” are endemic in this area. Ingo write, Leandro Melo de Sousa did extensive research about these species. While Hypancistrus zebra lives in shallow water, Hypancistrus sp. “L 174” occurs at a depth of 7 meters. Ingo assumes that Hypancistrus sp. „L 174“ uses an ecological niche to avoid Hypancistrus zebra.
Due to the lower water level in the Volta Grande, it can be assumed that Hypancistrus sp. “L 174” will be more exposed to the competition of Hypancistrus zebra. There is a serious risk that Hypancistrus sp. “L 174” will become extinct in nature. (In addition, the area is also endangered by a planned gold mine.)
In the hobby, Hypancistrus sp. “L 174” is much rarer than Hypancistrus zebra. The propagation of Hypancistrus sp. “L 174” is not nearly as productive and rearing much more protracted than that of Hypancistrus zebra.
Ingo calls to help preserve this species, at least in aquariums.
